REVOLVING DOUBLE-BOX COTTON-PRESS.

Application filed. November 22, 1911.

7 0 all QU/LOWt it may concern Be it known that I, Ti-mnnnns S. Genres, a citizen of the United States, residing at Columbus, in the county of lifluscogee and State of Georgia, have invented certain new and useful improvements in Revolving Double-Box Cotton-Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to revolving double box cotton presses and it consists in locating a plurality of press boxes above a continuous base portion or foundation and providing a plurality of devices for operating upon the cotton within said boxes, both of such devices being located above the base.

The invention resides further in providing means for lifting the boxes from the base, and also in lifting the boxes and rotating them while in an elevated position.

Furthermore, the invention resides in pro viding improved means for controlling the doors of the press boxes, improved means for retaining the cotton in the boxes while being compressed or packed, in providing hydraulic means for effecting the trainping and packing, and in other features of construction hereinafter described and claimed.

In the accompanying drawings forming part of this application: Figure 1 is a view of the double box press in side elevation. Fig. 2 is an end view thereof. Fig. 3 is a view of a portion of the device for operating the side doors of the boxes. Figs. 1 and 5 are detail views of the dogs for retaining the cotton within the boxes. Fig. 6 is a detail view showing one of the side doors opened. Fig. 7 is a detail partly in vertical section of the hydraulic device for lifting the boxes. Fig. 8 is a detail view showing one of the dogs for retaining the cotton in the boxes and the means for coiiitrolling the dogs. Fig. 9 is a view of the construction shown in Fig. 3 looking downwardly.

In carrying out my invention, 1 provide a structure'having a continuous and solid base portion or foundation 10 suitably supported as at 11., 12 and 13 and having uprights mounted upon said base portion 10 and stuoporting the upper portion of the structure. Three of these uprights are designated in the drawings as 14, 15, and 17.

Specification of Letters Patent.

Patented July 22, 1913.

Serial No. 661,810.

This upper portion includes transverse tim bers 18 and 19, 20 and 21. upon which the cylinders of the hydraulic tramping and packing devices 22 and a3 are mounted.

One of the important features of the pres ent device consists in the employment of hydraulic means for operating upon the cotton in both of the boxes.

Mounted centrally of the framework is a vertical shaft 25 carrying a framework 26 which is made rotatable in order to provide for the transfer of the boxes from beneath the tramping device to a point he neath the packing device.

The tramping device or plunger is indicated by 30 and the packing plunger by 31. The framework 26 comprises parallelly arranged side bars 32 and 253 connected by end timbers 3 1 and 235, and a similar framework 36 is carried by upright shaft 25 below the aforesaid framework 26. Diagonally arranged tie bars 37 extend from the outer ends of framework 36 to the side bars of frame 26 at points near the central portion thereof. A ball bearing 10 is provided on vertical shaft or column 9.5, and the frames 26 and 36 are carried thereon.

The press box 12 is shown in Fig. 1 as being located beneath the iramping device 30 and press box 13 as beneath packing plunger 31. Above press box 12 is a stationary receiving box 4141: carried by the framework and designed to receive the cotton as it is discharged from the condenser. The press boxes are provided with side doors 4-5 and 4:6 and with end doors i? and 18, the former being hinged to transverse member 39 (con stituting a bottom member), by means of hinges 16, and being secured by means of devices 1-9 operated by horizontal shaft 5 and cranks 51, together with chains 52.

hose chains 52 have connected with the ends thereof hooks 58 engaging notches in shaft 50. The chains are wound around the shaft last mentioned, against collars which latter have frictional contact with one or more surfaces on castings 58. By rea' son of this frictional contact, the rotation of the shaft before mentioned and the unwinding of the chain is effectively controlled; the frictional contact is in proportion to the n'essure on the doors. lfn Fi 3 9 a view of the construction of Fig. 3 appears in top plan. Shaft 50 held in a given position by means of a cotter pin 50,

and one end is received by bearing 50. By this means the collar is held against frictional surface 56 sufficiently close to prevent the sudden dropping of the doors when they are released. The end doors are raised and permitted to swing outwardly by vir tue of the connection of said doors with shaft 60, mounted in brackets 61 formed as shown in Fig. 2. Said shaft is in effect a rock shaft, and is provided with a crank 62 for operating the same. The cross pieces 65 of the end doors project beyond the edges thereof, and are engaged by socket members 66 carried by the side doors, whereby the end doors are effectively secured.

Pivoted and weighted dogs 67 are carried by the upper side portions of the press boxes, and upon the downward stroke of the plunger 31 are thrown outwardly by guard. members 68 and 69 carried by the plunger. These guard members are secured to transverse members 70 carried by the plunger pro-per. Stops 71 in the form of angle irons project outwardly a suiiicient distance to engage the upper edges of the boxes. The guard members cause the dogs to swing out of the path of the plunger during its down ward stroke, and permit them to swing into normal or operative position as soon as the bottom of the plunger has returned above the point of the dogs. On the tramping side, the plunger can pass up and down without touching the dogs. As the tramper forces the cotton down by the dogs, the latter are forced outwardly until the plunger has caried the cotton below them, when they swing into position over the cotton, as the tramper moves upwardly.

Central shaft or column 25 carrying the rotatable device or structure comprising frame 26 and frame 36 carries also trans verse member 89 to which the side doors are hinged. Lifting rods 75 and 76 are connected with cylinder 77 of the hydraulic lifting device '78 mounted centrally of the upper portion of the structure, and these lifting rods have connection with a collar 79 which is brought into contact with a ring 80 forming a part of ball bearing device 40. The operation of the hydraulic lifting de- Vice will therefore raise the rotatable device including frames 26 and 36 and permit of their rotation about shaft or column 25 as an axis, the press boxes being by this opera tion shifted from beneath one plunger to a point beneath the other. It is obvious that shaft 25 constitutes a guiding member for the frames 26 and 36, as well as an axis therefor.
